2. Design a three-bit counter like circuit controlled by the input w. If w = 0, then the counter subtracts 2 from its contents, wrapping around if the count reaches 0 or 1. Thus if the present state is 1 or 0, then the next state becomes 7 or 6, respectively. If w = 1, then the counter adds 2 to its contents, wrapping around if the count reaches 6 or 7. Thus if the present state is 6 or 7, then the next state becomes 0 or 1, respectively. Use positive edge triggered T Flip-Flops without Reset input. Show all the design steps. Write the Verilog code according to your design and simulate.

Fast Fourier Transform Concepts

The algorithm used to convert a sequence to its Discrete Fourier transform (DFT) is known as the Fast Fourier transform. It can be used for both DFT and IDFT (Inverse DFT) transformation.

Design a two-bit synchronous counter that counts the sequence 0.1,2 using T| * flip flop
In verilog a counter must be developed from 0 to 9999 with a reset and parallel loading. The reset will be a button in charge of returning the count to 0 when pressed.For this practice, the implemented circuit will only use a 7-segment BCD converter module, which will have to be managed between the different 7-segment displays at a given frequency.
Question 4: Design and implement a minimal 5 modulo up counter. It counts from 0 to 4 and repeats. Design the circuit such that, if the counter enters into the unwanted states: 5, 6 and 7, it should jump into state 0 on the next clock pulse.
Design a Moore FSM according to the below state diagram. As can be seen on the image, the FSM has a 1-bit input, and its initial state is the a. Draw the circuit of the FSM
Binary Counters Objective: Design, construct, and test a three-bit counter that counts up or down. A disable input D determines whether the counter is on or off. • If D=1, the counter is disabled and remains at its present count even thoughclock pulses are applied to the flip-flops. • If D-0, the counter is enabled and a second input, x, determines the directionof the count. • If x=1, the circuit counts the sequence 00, 01, 10,11 and the count repeats. • If x=0, the circuit counts the sequence 11, 10, 01, 00 and the count repeats. (Do not use D to disable the Clock) Note: Design the sequential circuit with D and x as inputs. Submission: Reports must include all schematics and cost of design. Compare your results with other solutions. (Costs, design....). Define why your design is better.

In what sort of circuit is it possible to choose binary information from a large number of input lines and send it to a single output line?
An asynchronous state machine has two inputs (X1 and X2) and one output (Z). The output is the same of the previous value if (X2=0) and (Z) equals to the value of (X1) if (X23D1). The circuit combines . OR- * .gate(s) ...... 2 1 3.
Design a circuit that takes three bits, X2, X1, X0 as input and produces one output, F. F is 1 if and only if 2<=X<=5 when X = (X2, X1, X0) is read as an unsigned integer. For example, if X2=1, X1=0, and X0=0, then the unsigned binary value is 100, which is 4, so the output would be 1. Your Assignment For This Problem Includes the Following Design the necessary circuit using Logisim to implement the situation described above. Use Kmaps for simplification. Be VERY careful to get the correct functions for your output before simplifying and designing the circuit with Logisim. You should minimize the circuit. Your circuit should have three inputs and one LED output. All inputs (X2, X1, X0) and output (F) should be labeled (in Logisim, not by hand). Please use these names to indicate the inputs and output so all projects are consistent. You should also include your name as a label on the circuit. Test your circuit to be sure it is working correctly.
In a sequential logic circuit, the next output is dependent on the previous output and the inputs. O a. Ob The only input is the clock signal. The background of the OC inputs. The sole data source is Od.
